Why are salt and sugar both able to dissolve in water, even though the solutes have different types of chemical bonding?

a. Everything can dissolve in water because water is considered a universal solvent.
b. Liquid water is cooler than solid salt and sugar, allowing them to dissolve easily.
c. Salt's ions and sugar's polar bonds are both attracted to the polar water molecules.
d. Small solutes like salt and sugar can fit in the spaces between large water molecules.

Tooth enamel consists mainly of the mineral calcium hydroxyapatite, ca_10(po_4)_6(oh)_2. trace elements in teeth of archaeological specimens provide anthropologist with clues about diet and diseases of ancient people. students at hamline university measured strontium in enamel from extracted wisdom teeth by atomic absorption spectroscopy. solutions with a constant total volume of 10.0 ml contained 0.726 mg of dissolved tooth enamel plus variable concentrations of added sr. added sr find the concentration of sr in the 10 ml sample solution in parts per billion = ng/ml. find the concentration of sr in tooth enamel in parts per million = mu g/g.
